Make "IterationIPC" MQ producer for VNF control messages

"IterationIPC" runner class is a consumer for MQ aware VNFs. A MQ aware
traffic generator can send "started", "finished" and "iteration"
messages.

This feature implements a MQ producer in the runner in order to send
messages to the VNFs. The messages implemented are:
  - "start_iteration"
  - "stop_iteration"
